Stresso, Tank stress Options

[CHLeong]

Hi Bros,
Would like to share with everyone what I am doing and investigating. I have been trying to understand the differences in environment for goldfish raised in a pond and tank. Noise is one area I am looking at and I understand that noise/vibration multiply many times in water media.
I am no scientist so feel free to rebuke my discoveries. As we understand that generally fishes react to the environment via their lateral line. So I placed my ear against the wall of my tank, and realised that they are living in a very noisy envirnoment. Vibration from the internal water pump, air pump, the sponge filter are generating a lot of noise. Its like blasting a mini compo in a bed room(tank) as compare to placing in a park(pond).
Bros, put your ear to your tank wall, off all equipment and realise how peaceful. Then turn on everything, do you find any difference?
Attach are pictures which I have made to reduce the noise in their environment.


I am in a middle designing a less stress tub for my fishes, that I will also share with everyone.

Comments?

You are definitely right that it will adjust itself eventually. However, I felt that since we spent dollars on our fishes, a less stress envirnoment will benefit our expensive collection.
With the modification, the noise/echo level has reduced but not eradicted. I intend to use a outside pump to draw the water into my top filer. I just came back from the stores, looking for a out-of-water pump but futile, lots of cheap taiwanese and chinese submersible.
Just in case bros here asked whether I check out the echo in the pond. I did visit the farm, initially the ah pek agreed to my request. But before I put my head in, he asked what kind of hair gel I used. My reply was "Catsby" and he stopped me. He doesn't wants his fishes killed as the advert of catsby where man had turned to skeleton. Ha..kidding...

yeap, i feel that the noise is very high too. i used to have used a OHF where the motor is above water but impeler in the water. almost no noise when press ear against tank. Then i day i bought a submersible pump for another ohf, and i thot the since 1 more filtration so can add more fish. so buy 3 more goldfish. however, i always not comfortable with the large noise generated by the sub pump. Anyway, few weeks later, somehow disease breakout and almost all the fishes died (2 fancy, 2 comet, 2 ryukin). i still think is overcrowding, but then there is always the nagging doubt in my mind whether the noise is a factor too.
but since so many ppl has no problem with the pump in water, so should be ok.

anyway, for sharing..
